They are both written in first person, they share
conflicts. First, in similarity,
they lived in close time periods (both lived in 20th century) and were very
poor. They went through a lot of struggle but in the end they achieved a lot.
They both share similar conflicts. These are both memoir stories written in
first person and talk about being young children.
In difference, No Gumption is about a boy who delivers newspapers to help
support his family and to learn how to have a job. His mother wants him to have
gumption so he won't end up the way his father was. In Barrio Boy, it is about
an immigrant who goes to school and learns English. I don't think the story
ever talks about him getting a job.
